CLOCK ATTACHM ENT.

SPECIFICATION forming part of Letters Patent No. 600,322, dated March 8, 1898.

Application filed December 24,1896. Serial No. 616,892. (No model.)

To @ZZ whom t may concern:

Be it known that I, JOSEPH SCHINDLER, a citizen of the United States, residing at Engle, in the county of Fayette and State of Texas, have invented certain new and useful Iniprovements in Glock Attachments; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to an attachment for clocks for indicating when the clock requires to be wound and will be understood from the following description and claim.

This invention consists of certain novel constructions, combinations, and arrangements of parts, all of which will be hereinafter more particularly set forth and claimed.

In the accompanying drawings, forming part of this specification, Figure l represents a front elevation of a clock embodying my invention. Fig. 2 represents a central vertical section through said clock just to the rear of the face-plate and looking forward. Fig. 3 represents a similar view to the rear of the mainspring, also looking forward. Fig. l represents a large detail perspective view of the pivoted lever. Fig. 5 represents a front elevation of a modiiied form of clock-face in which two independently-operated wings are employed. Fig. 6 represents a rear elevation of the same, and Fig. 7 represents a front elevation of another modification of my invention employed in connection with openface clocks.

A in the drawings represents the clock-cas ing; B, the face of the same; C, the mainspring of the clock mechanism,A and D the pivoted operating-lever. Said casing A and clock mechanism. C may be of any ordinary construction and material. The lever D is either pivoted under the mainspring O, as shown, or to one or the other side of the same. This lever comprises a lever proper, d, pivoted, as at cl', intermediate its ends and provided at one end with a segmental spring cl3, which extends into the path of the mainspring C when the same is fully expanded. The clock-face B is stamped or otherwise marked about its center with a plurality of colored sections b, which are adapted to be normally covered by a plurality of radiating wings e, mounted upon a disk E, which disk is pivoted upon a central sleeve c', through which the shafts of the hour and minute hands are passed. The face is also provided with a segmental slot b', through which projects the angular end f of the connecting-link F, said end f being secured to one of the wings e, so that when said link F is operated the disk E will be rotated, so that the win gs e will lie between the colored sections b, and thus expose the latter to view and indicate that the clock needs winding. The said link F is connected at its other end to the lever D by being passed through the slot in the face of the clock.

It will be observed from the foregoing description that when the spring C is nearly expanded it will contact with the spring cl3 and partly rotate Athe lever D upon its pivot d. This rotation will pull upon the rod F and thus rotate the disk E, as before described, and uncover the colored sections h, thus indicating that the clock needs winding.

In the construction of my invention shown in Fig. 5 I have provided two segmental slots, two colored sections, and two movable wings for covering said colored sections. Each of these wings is connected to its lever Din the manner above described and represents, respectively, the mainspring mechanism and the striking-spring mechanism, so that the condition of both of these springs is indicated thereby.

In Fig. 7, which shows an open-face clock which cannot be constructed in the center as heretofore described, two apertures h are formed in the bottom of the same andcovered by suitable pivoted shutters h2, which shutters are connected, respectively, to the mainspring and striking-spring levers D, so that the condition of said springs, respectively, may be indicated by the positions of said shutters over or away from the apertures 7i.

It will be observed from the foregoing description that the condition of the respective springs of the clock mechanism proper or the striking mechanism will be indicated a sufficient time before the springs have become fully expanded to enable the clock to be wound before it comes to a standstill.

Having thus described my invention, what IOO said lever and one arin of Which passes through the segmental slot in the clock-face and is connected to said Wings, substantially as described.

In testimony whereof I have signed this specication in the presence of two subscribing Witnesses.

JOSEPH SCHINDLER.
